The AutoChron 81000 Programmable Wall Light Switch Timer is identical to the Utilitec #0357930 (AmerTac) TMDW50L. Here are links to manuals for models prior to and as of 2012.

Before 2012

As of 2012

Timer is wired incorrectly.
Single pole wiring does not use the red wire. Red wire is capped off.

Related but not same problem:
In some 3-way wiring installations, if the power goes out, or if the bulb burns out, the timer can click. The lights do not blink because power is out or bulb is bad. Simply flip the 3-way switch to stop clicking sound. Then change light bulb, or wait for power to resume.

You might be looking for T-1032 or T-1034 500watt timer
Identify model number on following link, and then google-search that specific model.
Link to instruction manual appears for each timer.
http://waterheatertimer.org/Aube-timers-and-manuals.html

Honeywell Aube in-wall timers can be used for single-pole or 3-way applications.
Look at instruction manual carefully for 3-way wiring.
Timer can be used for incandescent, halogen and CFL with minimum wattage requirement.
Since Aube timers have internal battery, they cannot be exposed to freezing temperatures or high temperatures.

B) This timer is for single pole only and will not work for 3-way switching.
Timer does not have astronomical function.

C) If lights are blinking, timer is wired incorrectly.
Heres what to do
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires. Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

D) If you have trouble with programming, add a comment and say specifically where you are having problem for return comment.
I have programmed and tested this timer. Information above is accurate and tested.

Utilitec 7-day timer will only replace single-pole switch.
Single pole switch has two brass screws and a ground screw.

Links below show wiring for both Utilitec 7-day timers

If this is not your timer, then add a comment and specifically state which timer you have and which wires came off which screw on old switch.

The best way to start is to identify exactly which wires came off old switch.
How to wire
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 insulated wires. Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

You want to install Utilitec in-wall 7-day timer that has 4 wires: red, white, black and green.

You are replacing a single pole switch that controls a light or several lights.
There is not a second switch that controls same lights.

The switch has 3 wires.
Generally there are two insulated wires and a bare ground wire.
Add a comment any time.

Here's what to do:
I have tested these timers for wiring and programming.
Get started and instructions will make sense as you go.
Turn off circuit beaker to switch.
Remove old switch.

1) Timer-green-wire connects to bare ground wire using one of the yellow wire nuts included with timer. Put two wires together so they are even at ends. Put wire nut over wire ends. Rotate wire nut clockwise between fingers until very tight.

2) Switch has 2 insulated wires. Take switch wires and connect them to timer-black-wire and timer-red-wire using two more yellow wire nuts. Choose either one for now. You may have to reverse these two wires in a minute.

3) In back of electric box are white wires twisted together and covered with wire nut. Remove the wire nut, but do not untwist the white wires. Connect timer-white to these wires. Then put original wire nut back over white wires.

4) If electric box does not have white wires described in step 3, then connect timer-white to bare ground, along with timer-green wire.

5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires from step 2.

Press and hold the lock button on the wall control for 3 seconds. The light will stop blinking and your remotes will work.

Your door sensors are either bad or need simply to be aligned. They must be pointed at one another to work properly. Each of them has a small light that will be lit when they are pointed correctly.
